I'm wondering if the eeprom was affected when the orig. parts failed.
Normally I would referr you to the schemo to see at what point the OSD
charactor generator injected the OSD into the video. The video loss
would be after that point. I assume theres no small set up switch on a
board that may have been repositioned.
